Effect of variation in temperature and substrate on the germination and initial growth of Teak (Tectona Grandis)

Abstract

The effect of different temperatures and substrates on germination and growth of Teak seedling was studied. The germination percentage recorded after 9 weeks of sowing significantly higher at 30°C than at 25°C and 20°C. Vermiculite as a substrate gave highest germination but on par with that of Sand + Soil + FYM. The shoot length and number of leaves did not vary due to substrates, whereas, higher temperature (30oC) had favourable effect on these parameters compared to other temperature regimes studied.
